United States P21031 Delaware No Drawing. Filed Jan. 5, 1965, Ser. No. 423,603 12 Claims. (Cl. 424-40) ABSTRACT OF THE DISCLOSURE Toiletry and cosmetic compositions are provided which are smooth in texture and which impart a softening and soothing effect to the skin and the appendages of the skin.

The said compositions contain as an essential component from 0.1 to about 50% by Weight thereof of an alkylated polymer of an N-vinyl heterocyclic monomer wherein on an average at least of the N-vinyl heterocyclic monomer units in said polymer are alkylated with an alkyl group of from 10 to 42 carbon atoms.

This invention relates to emollient preparations containing alkylated polymers of heterocyclic N-vinyl monomers which impart a much smoother texture to the preparation together with a softening and soothing effect when applied to the skin and the appendages of the skin.

It is known that emollients and cosmetics for the skin and hair include all preparations for conditioning or embellishment such as cleansing creams, quick-liquefying creams, emollient creams, cleansing lotions, cream and paste rouges, lipsticks, anti-perspirants, facial masks, massage oils, hair .oils and creams, hair removers (epilating Waxcompositions), eye shadow, sunburn preventives, etc. Many of such preparations, other than normal soap bars, contain petroleum hydrocarbons in one form or another, such as mineral oil, petroleum (solid or liquid), and paraffin wax or a mixture of two or all of such hydrocarbons. Although these preparations are satisfactory for skins and scalps that tend toward oiliness, it is well established that the presence of mineral oils, liquid and solid petrolatums in such preparations is drying to the skin. As a consequence, such preparations require modification wit-h vegetable oils or with cholesterol, lecithin or an absorp: tion base. Paraffin and substances with similar proper-. ties are not recommended for use in cosmetic skin preparations because they may clog the pores and cause them to become enlarged or infected. Moreover, many of such preparations are neither sufficiently smooth in texture nor do they impart to the normally dry skin a softening and soothing effect.

The cosmetic industry has and is expending considerable amounts of money in research and development of a product or products which, when incorporated into toiletry preparations, will impart a much smoother texture as well as a softening and soothing effect on the skin and the appendages of the skin. The problems involved are manifold. The cosmetic chemist must consider the nature of the skin, i.e., whether normally dry or oily to which the preparation is to be applied. He must also consider the nature or character of the developed product, its compatibility with other components constituting the preparation and the effect ;when applied ot the skin or the appendages thereof.

It is the principal object of the present invention to provide toiletry preparations, i.e., emollients, cosmetics, and soaps, which are smooth in texture and which impart a softening and soothing elfect to the skin and the appendages of the skin.

Another object is to provide cosmetic preparations for the conditioning of nails of the toes and fingers.

. A further object isto provide cosmetic preparations for the conditioning and grooming of hair which will leave the hair soft, lustrous, alive-looking and manageable.

Other objects and advantages will become manifest from the following description.

We have discovered that products obtained by the alkylation of polymers of heterocyclic N-vinyl monomers or by the simultaneous polymerization and alkyl-ation of heterocyclic N-vinyl monomers and co-monomers thereof are excellent additives to soaps and cosmetic preparations of the cleansing, conditioning, and embellishing type which will impart a smooth texture as Well as a softening and soothing effect to the skin and skin appendages. The additives range from viscous oils to soft and relatively hard waxes. They can be used in place of, and in addition to, petroleum hydrocarbons, i.e., mineral oils, petrolatums and paraffin waxes. They are not only soluble in these petroleum hydrocarbons, but also soluble in other unctuous materials such as fatty acids; stearic, myristic oleic acids, etc.; glyceryl monostearate (Glycosterin); lanolin (wool fat); beeswax and other animal and vegetable waxes; higher alcohols, such as hexanol, myristyl alcohol, etc.; polyoxyalkylene glycols, e.g., polyoxyethylene glycol, polyoxypropylene glycol; methyl ethyl ketone, Cellosolve (2-ethoxyethanol), butyrolactone, etc, which are employed in toiletry preparations of this type. They are readily emulsified by the usual re-agents employed in toiletry manufacture. By virtue of this solubility, emulsifiability and broad compatibility With other components of the toiletry preparation, they substantially reduce or eliminate the drying tendency of mineral oils and petrolatums present in such preparations. Regardless whether the toiletry preparation contains any one or all of these petroleum hydrocarbons, vegetable oils', lanolin, and/or other unctuous components, or is free from such components, etc., the presence of the additive in such preparation imparts a much smoother texture to it with the attendant softening and soothing effect when applied to the skin and a softening effect when applied to skin appendages.

In some people, overproduction or underproduction of sebum causes excessively oily or excessively dry skin. In very cold weather the sebum congeals on its way to the surface and the skin becomes dry and chapped. In old age, sebum production drops very low and skin fibers lose much of their elasticity. Any toiletry preparation of the cleansing, conditioning or embellishing type containing the additive will keep the skin soft and pliable. Even though the toiletry preparation is removed from the skin or scalp by washing with water and soap, the soft and soothing effect persists. The same effect persists after several washings. The same effect is also noted when the additive is present in hair preparations. The hair remains soft, lustrous and alive-looking. In finger-nail preparations, the additive imparts a softening and smoothing effect. In lipsticks, the additive displays dye-binding properties as well as softening and soothing effects. It also retards drying out of the lipstick. In soaps and synthetic soap bars, the presence of the additive imparts a soft and pliable effect on skin and scalp and a soft effect on hair after rinsing with water. The same effect is felt after several rinses with water. Toiletry preparations, especially skin cosmetics, containing the additive and applied to the skin, resist the penetration of oils and of fine dust and other dirt particles which imbed themselves in the skin pores.

The unusual properties of the additive are not-clearlystearate, glycerine, the currently used emollients, hair- 3 oils and creams, etc., may be due to both the hydrophilic character of the component of the N-heterocyclic ring and the hydrophobic character of the alkyl chain or chains in said ring of the polymer molecule. The hydrophobic character imparts the solubility and compatibility in oils, fats, waxes, and other unctuous materials, as well as smoothness; Whereas the hydrophilic character may contribute to the softening and soothing eiiects.

The additives employed in accordance with the present invention are prepared by reacting one mole of a monomer or polymer of a (homopolymer or copolymer) of a a heterocyclic N-vinyl monomer with 0.5 to 4, preferably 1 to 3, moles of an a-olefin of from 10 to 42 carbon atoms in solution of an organic solvent common to the monomer and its polymer (homopolymer or copolymer) in the presence of 0.025 to 0.30 mole of an organic peroxide catalyst per mole of iii-olefin at a temperature ranging from 100 to 200 C. for a period of time ranging from 3 to 60 hours. The percent of a-olefin reacted is determined by the percent of the a-olefin consumed and may range from about 50% to 100% of the a-olefin charged. Alkylated polymers of heterocyclic N-vinyl monomers with emollient properties are obtained in which a minimum of 25% to a maximum of 400% of the monomeric units in the polymer are alkylated. In other words, alkylated homopolymers are obtained containing an average of 0.25 to 4 alkyl groups of 10 carbon atoms per monomer unit. In the case of a copolymer of 60% by weight of heterocyclic N-vinyl monomer and 40% by weight of a non-heterocyclic monomer, alkylated copolymers with emollient properties are obtained in which a minimum of 30% to a maximum of 240% of the heterocyclic N-vinyl units in the copolymer are alkylated, i.e., containing at least 0.25 alkyl groups of 10 carbon atoms per monomeric unit in the copolymer. In alkylating such copolymers to obtain the best emollient properties, it is preferred that 1-3 moles of a-Olefin be reacted with one mole of copolymer to yield an alkylate in which at least 30% of the heterocyclic N-vinyl units in the copolymer are alkylated. The resulting solution of the alkylated polymer is subjected to vacuum distillation to remove the organic solvent. The residue, alkylated polymer, ranges from a viscous oil to a soft and substantially hard wax.

The homopolymers of heterocyclic N-vinyl monomers, which are alkylated with an a-olefin of from 8 to 42 carbon atoms and employed as additives, include homopolymers of N-vinyl suecinimide, N-vinyl diglycolylimide, N- vinyl glutarimide, N-vinyl-3-morpholinone, N-vinyl-- methyl-B-morpholinone, N-vinyl-5-ethyl-3-morpholinone, and N-vinyl lactams having the following formulae:

The individual homopolymers of the foregoing heterocyclic N-vinyl monomers may be alkylated as such or in admixture. The proportions constituting the mixture are immaterial since such mixture of homopolymers is readily alkylated and yields a product with emollient properties. However, where a mixture of any one of the foregoing heterocyclic N-vinyl monomers is copolymerized prior to alkylation with an a-olefin, with a non-heterocyclic monomer containing a polymerizable vinyl group, it is preferable that the comonomer mixture contain at least 60% by weight, i.e., from 60% to by weight of any one of the foregoing heterocyclic N-vinyl monomers with up to 40% by Weight, i.e., from 5 to 40% by weight of a non-heterocyclic monomer. The non-heterocyclic monomers containing a polymerizable vinyl group which are copolymerized with any one of the foregoing heterocyclic N-vinyl monomers, prior to alkylation, including vinyl ester monomers such as vinyl acetate, vinyl propionate, vinyl butyrate, vinyl isobutyrate, vinyl lactate, vinyl caproate, vinyl caprylate, vinyl oleate, and vinyl stearate; vinyl chloride; vinylidene chloride; acrylonitrile; styrene; acrylic acid; 'acrylate ester monomers of the formula CH CHCOOR wherein R represents either a straight or branched alkyl of from 1 to 18 carbon atoms or an alkoxyalkyl in which the total number .of carbon atoms in the alkyl groups range from 3 to 6. As examples of such acrylate esters the following are illustrative: methyl, ethyl, propyl, isopropyl, butyl, isobutyl, s-butyl, Z-methyl-l-butyl, 3- methyl-l-butyl, Z-ethyl-l-butyl, amyl, 3-pentyl, 2-methyll-pent'yl, 4-methyl-2-pentyl, hexyl, Z-ethylhexyl, heptyl, 2-heptyl, octyl, 2-octyl, nonyl, 5-ethyl-2-nonyl, decyl, 2- methyl-7 ethyl-4-undecyl, dodecyl, tetradecyl, hexadecyl, octadecyl, 2-methoxyethyl, 2-ethoxyethyl and 2-butoxyethyl acrylate; methacrylate monomers such as methacrylic acid, methyl methacrylate, cyclohexyl methacrylate, isobutyl methacrylate, isoamyl methacrylate, fi-methoxy ethyl methacrylate and a-(o-chlorophenyl) ethyl methacrylate, B-phenoxyethyl methacrylate, a-phenylethyl methacrylate, phenyl methacrylate, o-cresyl methacrylate, pcyclohexylphenyl methacrylate, 2-nitro-2-methyl propyl methacrylate, diethylaminoethyl methacrylate, ethylidene acetate methacrylate and glycidyl methacrylate, including esters of halo acrylic acids, such as methyl-a-chloroacrylate, ethyl-a-chloro-acrylate, phenyl-a-chloro-acrylate, a-ethylacrylic acid; methacrylonitrile; acrylamide; methacrylamide, as well as N-alkyl and N-aryl substituted acrylamides such as N-methyl acrylamide, N-ethyl acrylamide, N-propyl acrylamide, N-n-butyl acrylamide, N-ndodecyl acrylamide, N-n-octadecyl acrylamide, N,N-dimethyl acrylamide, N,N-diethyl acrylamide, N,N,-di-n butyl acrylamide, N,N-diisobutyl acrylamide, N-cyclohexyl acrylamide, N,N-dicyclohexyl acrylamide, N- phenyl acrylamide, N-p-nitrophenyl acrylamide, N-ocnaphthyl acrylamide, N-fi-naphthyl acrylamide, N-methyl-N-p'henyl acrylamide, N,N-diphenyl acrylamide, N- benzyl acrylamide, N,N-dibenzyl acrylamide; and grafted monomers on the polyvinyllactam of the type disclosed in United States Patents 3,029,219; 3,035,009; 3,036,033, and the like. Both the homopolymers and copolymers should have a K value of 10 to 140 for the alkylation reaction, preferably of 20 to 100. r

It is to be noted that the nature or character of the non-heterocyclic polymerizable monomers is immaterial so long as such monomers are capable of copolymerization in the aforestated proportions with the heterocyclic N-vinyl monomers and yield copolymers which can be alkylated.

In the alkylation of the polymers of heterocyclic N-vinyl monomers, i.e., homopolymers and copolymers, any a-olefin having a molecular weight from about 140 to about 588 may be employed in the alkylation reaction. In other words, alpha-olefins (straight chain or branched), ranging from l-dodecene, l-tetradecene, l-hexadecene, l-heptadecene, l-ocetadecene, l-nonadecene, l-eicosene, l-docosene, l-tetracosene, l-pentacosene to trimerized a-tetradecene may be used.

While linear a-olefins are preferred because of their. commercial availability, numerous isomers of a-olefins ranging from l-pentene to l-pentacosene as well as polybutenes may also be employed in the alkylation reaction. The only precaution required in such case is that the isomer contain an ethylenic unsaturation in the a-position thereof.

Instead of employing any one of the foregoing individual a-olefins; a mixture of commercially available linear a-OlCfiHS produced by cracking petroleum wax orby polymerizing lower olefins may also be used as the alkylating agent. The commercial product composition contains a mixture of linear olefins ranging from 11 to 15 carbon atoms, and as high as 15 to 22 carbon atoms.

In lie-u of the individual a-olefins of from 10 to 42 carbon atoms or mixtures thereof, alkylated polymers of heterocyclic N-vinyl monomers suitable for the purpose of the present invention are also obtained by alkylating the polymer (homoand co-polymer) with at least 5 moles to as high as 16 moles of ethylene for each mole of polymer to yield an alkylate wherein the ethylene propagates itself to a minimum average chain length of 10 carbon atoms. A minimum average chain length of 10 carbons is also obtained by alkylation with l-p-ropene, l-butene, l-pentene, l-hexene, l-heptene, l-octene or l-nonene. In determining for each mole of polymer the required number of moles of such oz-Olefin, i.e., from 2 to 9 carbon atoms to obtain the minimum average chain length of 10 carbon atoms, the following formula may be used:

wherein M represents the number of moles of the -olefin and C represents the number of carbon atoms in the a-olefin. I Inste'adof employing ethylene as the alkyl-ating agent, chlorinated and/or fluor'inated a-olefins such as, for example, dichlorovinylidene fluoride, chlorovinylidene fluoride, chlorotrifluoroethylene, tetrafluoroethylene, vinylidene fluoride and the like may be used.

In the alkylation of polymeric heterocyclic N-vinyl compounds with an alpha-olefin or mixtures thereof, an organic solvent is employed which is common to the polymer and alpha-olefin(s). As solvents, various alcohols such as methanol, ethanol, propanol, isopropanol, butanol, sec-butanol, amyl alcohol, hexanol, 2-ethyl-1ahexanol, ethylene glycol, 1,2-butanediol, 4-butanediol, etc. may be employed. Other solvents such as d-iacetone alcohol, diethylene glycol, ethylene glycol monomethyl ether acetate, methylene chloride and the like may also be employed. It is to be noted that the nature or character of the organic solvent is immaterial so long as it is a liquid, forms a solution with the polymer and alkylating a-olefin(s), and is not susceptible to alkylation.

The amount of organic solvent employed is not critical. Any amount which will yield a solution of the polymeric material and a-olefin(s) will suflice. However, for purposes of expediency, for every part by weight of solid homopolymer or.copolymer of N-vinyl lactam, from 2 to 10 parts of organic solvent, either by volume or by weight, are sufficient to yield a workable solution.

As peroxide catalyst (initiator) for the alkylation reaction, any one of the known tertiary-alkyl organic peroxides such as, for example, t-butyl hydro-peroxide, di-t-butyl peroxide, t-butyl perbenzoate, di-ti-butyl peroxide, t-butyl perbenzoate, di-ti-butyl perphthalate, t-butyl-pentamethylethyl peroxide, tbutyl-triphenylmethyl peroxide, di-t-amyl peroxide, bis-(triethylmethyl) peroxide, bis-(triphenylmethyl) peroxide, 2,5dimethylhexyl-2,S-dihydro-peroxide, 2,5 dimethyl-2,5-di(t-butyl peroxy) hexane, 2,5-dimethy1- hexyl-2,5-di(peroxy benzoate), and the like may be used.

The alkylation procedure for both the homopolymers and copolymers of the foregoing heterocyclic :N-vinyl monomers is more fully described in the co-pend-ing applications of Ashot Merijan, Frederick Grosser and Eugene Hort, Ser. No. 340,786, filed on Jan. 28, 1964, entitled Process of Alkylating Polymer N-Vinyl Lactams, now abandoned, the complete disclosure and teachings of which are incorporated herein by reference thereto. Alkylated homopolymers and copolymers with emollient properties are also obtained by the procedure described in the copending application of Ashot Merijan and Frederick Grosser, Ser. N0. 358,406, filed on Apr. 8, 1964, and entitled, Simultaneous Polymerization and Alkylation of Heterocyclic N-Vinyl Monomers, now abandoned, the complete disclosure and teachings of which are incorporated herein by reference thereto.

Where it is desired that the alkylated polymer be in solution of a mineral oil of the type employed in toiletries, the alkylation of the polymers or the simultaneous polymerization and alkylation reaction of the monomer(s) is preferably conducted in the presence of hexanol. As the latter is being removed during vacuum distillation, it is replaced with a refined mineral oil and the resulting solution of the alkylated polymer employed as the additive. Any refined mineral oil used by the pharmaceutical and cosmetic trade is ideally suited as a replacement during the removal of the hexanol by vacuum distillation.

The following examples will show how some of the alkylated polymeric N-vinyl lactams are prepared.

In analysis of the contents, no trace of N-vinyl-2-pyrrolidone or N-vinyl-3-morpholinone were found but only the presence of 11.6% of a-octadecene was detected which indicates a residual of 76 grams unreacted olefin. The contents were then transferred into a two-liter flask and the solvent stripped in vacuum and substituted with 434 grams 100 sec. solvent. The final 50% solution was a clear amber liquid weighing 860 grams.

The contents were then cooled and analyzed and found to contain only a trace of N-vinyl succinimide and 3.66% (equivalent to 15.0 grams unreacted only) of u-eicosene by weight of the solution. Then 244.5 grams of 100 sec. solvent were added and the solvent stripped in vacuum. The final 50% solution obtained was clear and weighed 485 grams. (Theory: 489.0 grams.)

EXAMPLE XII Into a one-liter, four-necked flask equipped with stirrer, thermometer, nitrogen inlet and reflux condenser, after a thorough nitrogen purge, the following ingredients were charged and heated:

The contents were then cooled and analyzed. The analysis showed the total absence of the monomer and only 3.0% (equivalent to 12.0 grams unreacted) of a-eicosene. The solvent Was then stripped in vacuum and substituted with 186 grams 100 sec. solvent. The final 50% solution in the 100 sec. solvent was clear and weighed 371 grams. (Theory=372 grams.)

The alkylated polymers of heterocyclic N-vinyl monomers prepared as above described, and in accordance with the foregoing illustrative examples, are soluble in all of the unctuous materials used in toiletry preparations such as vegetable and mineral oils, fatty acids, fatty acid esters, waxes, polyoxyalkylene glycols, higher alcohols of from 6 carbon atoms and up, including compounds having similar boiling points of the type employed in the alkylation reaction. They are also partially soluble in hot lower alcohols such as ethanol and propanol. Solutions of the product of Example I in hot ethanol and in hot propanol are cooled to room temperature, the ethanol contains about 0.1% of alkylated polymer, whereas the propanol contains about 0.3% of the alkylated polymer. Their partial solubility in such alcohols provides an excellent means for incorporation into non-unctuous materials. The alkylated polymers are added at any suitable stage of conventional toiletry manufacture. In other words, if the toiletry preparation comprises an unctuous base the alkylated polymer is dissolved in such base by gentle heating and stirring until solution is attained. For example, where such unctuous material is a liquid such as mineral oil, myristyl alcohol, etc., the alkylated polymer is dissolved therein'at room temperature with or without gentle heating and stirring. Where such unctuous components are solids such as solid petrolactams, paraflin wax, natural and synthetic waxes, fatty acid, fatty acid esters, lanolin, etc., they are first heated to the liquid state and the alkylated polymer dissolved therein with stirring. The temperature of heating may vary from 50 to C., depending upon the nature or character of the unctuous material. If a water phase is included in such preparation such as triethanolamine, borax, sodium or potassium hydroxide, and any other water soluble components, the oil phase is added slowly to the water phase or vice versa with good agitation.

The amount of alkylated polymer that is employed to effect the desired results (smoother texture with softening and soothing effects) ranges from about 0.1% to about 50% by weight based on the total weight of the completed toiletry preparation. The alkylated polymers are added at any stage of manufacture of cold creams, cleansing creams, emollient creams, finishing creams, skin-softening lotions, hand cleaners, lubricating creams, overnight creams, iabsorption-base creams, hand creams and lotions, foot creams, baby creams, baby skin oils; special creams, such as astringent creams, bleaching creams, acne creams, protective creams (industrial creams), vanishing creams, foundation creams, brushless shaving creams, shaving preparations, after-shave lotions and sprays, medicated creams, deodorants and anti-perspirants, such as deodorant creams and lotions, roll-on deodorants, sunburn preventives, suntan preparations, paste or lotion rouges, cream rouges, massage oils, facial masks, depilatories, i.e, hair removers (epilating wax compositions) and hair removing creams, paste or lotion face make-up, face powders; eye makeup, i.e., eye shadows and eyebrow creams; fingernail creams and cleaners, hair bleaches and tints, cuticle softeners, hair conditioners, wave sets, hair dressings, hair brilliantines; hair oils, hair sprays, creams and shampoos, nail polish removers, lipsticks, perfume sticks, facial soaps, synthetic soap bars, antiseptic soaps (tincture of green soap), insect repellents, protective hand creams, waterless hand cleaners, dentifrice, pet shampoos, bath tales, and the like.

From Examples XIII to XXXV it is evident that the alkylated polymers (homopolymers and copolymers) of heterocyclic N-vinyl monomers are not only soluble in, but also compatible with, a large variety of currently used and acceptable toiletry carriers (cosmetics and soaps) to yield compositions having new, novel and desirable properties.

Because of their softening and soothing effects, the alkylated polymers may be employed in the preparation of pharmaceutical salves, ointments and suppositories. Such preparations may contain the usual antiseptic, germicidal and medicinal agents.

. 16 a I The alkylated polymers display their desirable emollient effects in all types of ointments, salves, lotions, antiseptics, disinfectants, and other medicinal preparations for external use. The alkylated polymers are especially adaptable in the preparation of non-irritating detergent emulsions as skin cleansers for removing grease and oils from the skin. They manifest their softening and soothing effects when incorporated in hemorrhoidal preparations. They can be incorporated into unctuous materials and employed as lubricants to aid the passage of cathethers or enema tubes. They can be incorporated into salves and ointments used in the treatment of burns. Due to the water insolubility of the alkylated polymers, a continued softening (emollient) effect is noted even after several washings of the skin with soap and water.

While the present specification has shown the new and useful application of a large class of alkylated polymers of heterocyclic' N-vinyl monomers in cosmetics and soaps, alkylated polymers (homoand co-polymers) of other heterocyclic N-vinyl monomers containing a a o I II group in the ring may be employed as additives in accordance with the present invention.
